Oscillating mechanical fire grate used for lamellated decoupling burning furnace

Abstract

The invention relates to a reciprocating-oscillation type mechanical grate used with a layered decoupling burning furnace, which comprises a reciprocating-type upper grate with a grid structure, and an oscillating type lower grate, and a lower grate. The left end of the reciprocating-type upper grate is overlapped with the upper end of the oscillating type lower grate. The right end of the reciprocating-type upper grate is supported by and connected with a supporting rod. The lower end of the oscillating type lower grate is supported by and connected with a supporting beam. The lower end surface of the oscillating type lower grate is connected with a transmission mechanism. Under the drive of the transmission mechanism, the oscillating type lower grate oscillates reciprocatingly and alternately in clockwise and counterclockwise directions, around the upper part of the supporting beam as a center, with an oscillation included angle of 10-40 degrees. The grate realizes the mechanical automation of layered decoupling burning furnaces with various specifications, increases the efficiency and environment-friendly performance, and solves the problems of the prior layered decoupling burning furnace with large capacity (above 700kw), such as large size, uneasy operation, and poor stability in environmental protection.

Description

technical field [0001] The invention belongs to a fire grate in the field of raw coal combustion equipment, in particular to a reciprocating swing mechanical fire grate used in a layered decoupling combustion furnace. Background technique [0002] At present, there are few technologies in my country to solve the pollution discharge of small and medium-sized industrial boilers. The ZLCN 95 102081.1 applied by the applicant in 1995 has a very outstanding effect on solving the high-efficiency and low-pollution discharge of small and medium-sized mechanical floor-fired boilers with a large amount of consumption. , after continuous improvement in practical applications, the layered decoupling combustion furnace below 700kw has been very mature, but at present, the layered decoupling combustion furnace above 700kw still has a large footprint, difficult operation and insufficient environmental stability advanced questions. [0003] For the grate structure of layered decoupled combus...
